  • THERMAL BLOCK WITH BUILT-IN THERMOELECTRIC ELEMENTS
    Publication number: 20130137144
    Abstract: Rapid and uniform temperature changes in the wells of a microplate or any thin-walled plate that contains an array of reaction wells, or in the channels of a multi-channel microfluidics device, are achieved by the use of a thermal block with thermoelectric heating/cooling elements built into the block, or by the use of a thermal block with wedges protruding from its lower surface, with thermoelectric elements placed in surface contact with the angled sides of each wedge.

  • THERMAL CYCLER WITH SELF-ADJUSTING LID
    Publication number: 20120279954
    Abstract: A thermal cycling instrument for PCR and other reactions performed on multiple samples with temperature changes between sequential stages in the reaction procedure is supplied with a thermal block to provide rapid changes and close control over the temperature in each sample vessel and a pressure plate incorporated into a motorized lid that detects anomalies in the reaction vessels or in their positioning over the thermal block, and automatically adjusts the plate position to achieve an even force distribution over the sample vessels.
